org.apache.stanbol.enhancer.servicesapi.helper.InMemoryBlob
Holds the parsed data in an byte array. Parsed byte[] are NOT copied, Strings are encoded as UTF-8 and {@link InputStream} are copied by using {@link IOUtils#toByteArray(InputStream)}.
The default mime-types (if null is parsed as mimeType) are for Strings "text/plain" and in all other cases "application/octet-stream".
